After a brief appearance before a magistrate judge in Philadelphia, the man known as “Johnny Doc” was released on a $50,000 recognizance bond after agreeing to limit his contact with potential witnesses — including those in his union — to work-related conversations.

He had arrived hours earlier in a cobalt blue suit, and was unusually tight-lipped, saying only, “See you at 1:30,″ to the throng of reporters and cameras as he ducked into the building with his lawyer, Henry E. Hockeimer Jr.

But there were glimpses of the union leader’s personality: Just before the early afternoon hearing opened, Dougherty approached the prosecutors looking to convict him, introduced himself, and shook their hands. One replied: “It’s all business.”

As he left the building hours later, Dougherty, 58, told reporters he couldn’t answer their questions, but hinted he would have much more to say in the near future.

“You’ll start to get all my personal feelings as all the factuals come out," he said before pushing through to a car waiting on Market Street.

Dougherty was joined by two other indicted members of Local 98 of the International Brotherhood of Electrical Workers — political director Marita Crawford, 49, and employee Niko Rodriguez, 27 — in pleading not guilty Friday to counts including conspiracy, embezzlement, tax fraud, and theft before U.S. Magistrate Judge Elizabeth Hey. Anthony Massa, a 65-year-old Philadelphia-based contractor, also entered his plea and was released like the rest on a $50,000 recognizance bond.

The proceedings were largely a formality, but it was Dougherty’s first public appearance since prosecutors unveiled the 116-count indictment in the case.

The union boss’ house on Moyamensing Avenue in South Philadelphia remained dark for much of the day Wednesday, the day the charges were unsealed. More than two years earlier, though, when FBI and IRS agents searched the building, Dougherty stood outside holding court in a 76ers ball cap, an untucked white button-down shirt, and shorts, and nonchalantly served iced tea and doughnuts to reporters gathered outside.

He repeatedly denied any wrongdoing that day, and has repeated that refrain as the investigation continued. Union spokesperson Frank Keel went further Friday, calling the government claims that Dougherty enriched himself on the backs of union members "a crock” and an attempt by prosecutors to turn Local 98′s membership against the man who has led them since 1993.

“The membership has never been more strongly behind John ... and that’s not going to change,” he said as he stood outside the courthouse in the bitter cold to greet Dougherty’s codefendants as they arrived.

Brian J. McMonagle, the lawyer representing Philadelphia City Councilman Bobby Henon, also derided prosecutors’ allegations as an attack on organized labor a day earlier, after his client entered his own “not guilty” plea.

“If you look around this city, you’ll see a lot of skyscrapers,” McMonagle said Thursday. “They’re built by hardworking union men and women. Unfortunately, [this] indictment is a reflection of the fact that the government wants to make sure that the political power in this city stays inside those buildings, and not with the men and women who built them.”

Prosecutors allege Dougherty and other union officials drained Local 98 of more than $600,000 over six years to fix up their homes and pay for travel, groceries, and restaurant goods.

They portrayed Henon as a puppet, swept into Council in 2011 with money from Dougherty’s union, then later used as a tool by the union boss to benefit his personal interests.
